Our solar system is the one new member. A dwarf planet from the edge of the solar system,
Scott Shepherds from the Carnegie Institute in Washington, DC, Vick's Chad Trujillo of the Gemini Observatory in Hawaii. Have reported the discovery of a new dwarf planet named 2012 VP 113 (2012 VP113) which orbits outside the solar system. May be part of the objects in the Oort cloud layer. This survey also revealed that there may be a planet that is several times larger than the Earth is a lot waiting to be discovered
previously unknown star, astronomers Sedna. The objects in the solar system that is as far as known, but 2012 VP 113 is closest point in the orbit of Sedna away again. Becomes the object in the solar system as far as possible the new
astronomers discovered Sedna in 2546, after the validation orbit. Astronomers of the object Sedna inner Oort cloud objects. The objects, comets originated. This is the first object is known
that the discovery of 2012 VP113 make this object become the Oort cloud in the second floor. The perihelion of the orbit of 2012 VP113 is 80 times the distance between Earth and the sun. Or about twice the average distance from the Sun to Pluto
was discovered. Shepherds and the Trujillo. Use a webcam camera (DECam) mounted on the camera's OAO 4m in Chile to explore. Camping is a great camera, the imaging camera in the camera's widest range in size from 4 meters to all. Ideal for the faint objects over a wide area. The position measurement to find the orbit and surface properties of the 2012 VP 113 from the survey with a Magellanic lane Observatory La Campana 6.5 meters in Chile
Shepherds and. The Trujillo calculate that. In the Oort cloud layer should be an object that orbits like Sedna and 2012 VP 113 with a diameter of more than 1,000 kilometers, about 900 stars, an amount greater than the Kuiper belt and the main asteroid belt
, the Sedna and. 2012 VP 113 were found, while in the perihelion of the orbit. Both satellites have a perihelion distance of several hundred astronomical units. If the range is too faint undetected. Astronomers both commented. There may be a global or large objects may be larger than the orbit in the same area that are still waiting to discover the
scientists proposed a theory about the origin of the Oort cloud top three. One theory says Wandering stars have planets that are cast out of the giant planets. The planet is passing through the region of the Kuiper belt. Sent gravity disturbing objects in the Kuiper belt, knocking back well into the inner Oort cloud. Currently, the planet may still be in one place at the outer edge of the solar system
, said two theories. A stellar neighbor, the one-pass approach. Then I let the object is moving in the inner Oort cloud is
a third theory. Explained that the objects in the Oort cloud layer in truth, it is a planet orbiting a star that had been seized by the army in the sun to come closer together in the past
the Oort cloud objects more. Will help to determine which Theory is correct except for the inner Oort cloud objects. Not far away, the outer Oort Cloud. Which is about 1,500 astronomical units from the sun. Objects in this area has been influenced by the star side effects. Make changes to the orbit of the charges. Many of the incoming comets appear to be seen. It is an object of the outer Oort cloud. The objects in the Oort cloud layer is influenced by the gravity of the star, the others not as much as the outer Oort cloud. Orbits are stable and traditional than Scott Shepherds, said the search for objects in the Oort cloud layer, it must continue. Since the subject such as this will help astronomers better understand the formation and evolution of the solar system is huge.
